“While our web-based systems were briefly affected, our delays today have been primarily caused by air traffic congestion associated with runway construction and runway configuration in Honolulu,” a spokesperson told KHON2.

Hawaiian Airlines customers who are still having issues on the website may contact their web support at 1-866-586-9419.

The Hawaii Department of Transportation says this was not an airport issue.
